I have two PCs both running Ubuntu 8.10, at home and at shop, both use Mozilla Thunderbird as email client. I want to have those two PC's email clients to have same address book, looks and setting and most importantly same content. And I have, how?

This is what you need :

• A synchronization application
• A portable USB Harddisk/Thumbdrive/Flashdisk
  

Remember to back up your files before doing this, I won't take any responsibility if anything bad happens to your files.

This is what you do on your first PC (the one that contains your latest email) :

1. install Unison, via Application → Add/Remove → search for Unison, after installed you can find it in Application → accessories.

2. Make a new profile e.g. email,

3. Look for Thunderbird profile, by default it's located in /home/username-pc1/.mozilla-thunderbird/xxxxxxx.default/ , in Nautilus (file explorer) you need to press CTRL+H to show hidden files.

4. Copy all files in it to your portable hard disk, example /your-usb-name/Thunderbird/

5. Start Unison, it will ask for your two folder/files location that you want to be synchronized, in this case it would be :

   1. home/username-pc1/.mozilla-thunderbird/xxxxxxx.default/

   2. /your-usbflashdisk-name/Thunderbird

6. since it is your first time synchronizing, Unison will ask what to do :

• Action → Resolve all Conflict in Favor of First Root

• Go, that will synchronize from location 1 to 2.

Now in your second computer ;

1. Install Unison

2. Start Unison, it will ask for your two folder/files location that you want to be synchronized, in this case it would be :

   1. home/username-pc2/.mozilla-thunderbird/yyyyyyy.default/

   2. /your-usbflashdisk-name/Thunderbird

3. since it is your first time synchronizing, Unison will ask what to do :

• Action → Resolve all Conflict in Favor of Second Root

• Go, that will synchronize from location 2 to 1.

Now you got two exactly identical Mozilla Thunderbird-s on your PCs.

That's it. After that Unison will compare and recognize which files are newest every time you run it.

This method can be applied to synchronize any files you may have : document files, Firefox profile, etc.

Happy Synchronizing!
